President Zelensky has restated Ukraine's gratitude to the United States for its support since the Russian invasion, after President Trump accused him of being ungrateful in an angry clash at the White House. Mr Zelensky said Kyiv was still willing to sign a minerals deal with Washington but that his country needed US security guarantees. He said Russians were still killing Ukrainians and peace could only come when Ukraine had a strong position for negotiations. Mr Zelensky has landed in Britain and is due to meet the Prime Minister Keir Starmer ahead of a summit of European leaders in London.
